If I understand your question correctly, I believe you are solving (5 - z)/z = 9. If you are, then here are the steps below:
(5 - z)/z = 9 Given
(5 - z)/z * z = 9 * z Multiply both sides by z
5 - z = 9z Simplify
5 - z + z = 9z + z Add z to both sides
5 = 10z Simplify
5/10 = 10z/10 Divide both sides by 10
1/2 = z Simplify
z = 1/2 or 0.5 Symmetric property
